PATENT OEEicE EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 770,001, datedSeptember 13, 1904.

Application led July 27, 1903.

To wl whom, 7115 may con/cern.'

Be it known'that I, FRANCIS X. GARTLAND, acitizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inEyeglasses, of which the following is a specification.

This invention relates to eyeglasses, and more especially to the meansfor securing the spring and guards in manner to obviate the use ofscrews, which are constantly liable to work loose and allow the parts tobecome detached, and is an improvement on the Patent No. 733,639, issuedto me July 14, 1903, and my application, Serial No. 138,174, filedJanuary 7, 1903. As in the previous inventions, the spring and guardsare united and secured in a receptacle at the top of the posts, but in amore simple, inexpensive, and practical manner, as will be fully setforth in the specification.

rIhe invention is illustrated in the accompanying drawings, in which-Figure 1 shows a pair of eyeglasses having posts with inclosedreceptacles for the spring and guards. Fig. 2 is an end view of thereceptacle. Fig. 3 is a section on line Fig. 2, with the interlockingprojection on the spring and the locking-plate inserted below the guard.Fig. 4 is a section on line .c m, Fig. 2, with the interlockingprojection on the guard and thelocking-plate inserted above the guard.

Similar figures of reference indicate similar parts throughout theviews.

The lenses 1 are secured to posts 2 in any suitable manner, asillustrated, or to frames, as shown in the previous inventions. Theposts 2, as in the previous inventions, have receptacles 3 at their topscomposed of top walls 4, bottom walls 5, and side walls 6 7, leavingopen ends 8 9 for the insertion of the spring 10 and guard 11. InFig. 3the spring 10 is above the guard 11, and a projection 12 on the guard 11passes through an aperture 13 in the spring 10'and enters an aperture 14in the top wall 4, while locking-plate 15 is forced into the receptaclebetween guard 11 and wall 5, securing all the parts from. displacementuntil the locking-plate is with- Serial No. 167,066.

drawn, an offset 16 in guard 11 assisting in its security. Oppositeaperture 14 in wall 4 is an aperture 17 in .wall 5.

As in some instances and for special forms of guards it is moreadvantageous and desirable to have the projection 12 formed on thespring than on the guard, the manner.

V10 and wall 4, and the offset 16 is on spring 10. Thus it will be seenthat by having apertures 14 and 17 opposite, the post and its receptacleis adapted for use with either the spring having projections and theguards having apertures, or vice versa, and projection 12 may be placedin aperture 14 or 17 to suit any combination of springs, guards, andinterlocking projections.

I claim- 1. In eyeglasses, the combination of posts having receptaclescomposed of top, bottom and side walls forming open ends, with memberscomprising a spring and guards, a projection on one member which passesthrough an aperture in the other member and into an aperture in a wallof the receptacle, and locking-plates inserted in the receptacles toretain the spring, the guards and the projections in position in thereceptacle.

2. In eyeglasses, posts having closed receptacles except as to theirends, which are open, a spring having projections passing through theguards, and into a wall of the receptacles, and locking-plates insertedin the receptacles to retain the spring, the guards and the projectionsin position therein.

3. In eyeglasses, posts having closed receptacles except as to theirends, which are open, guards having projections passing through thespring and into a wall of the receptacles, and locking-plates insertedin the receptacles to retain the guards, the spring and the projectionsin position therein.

4. In eyeglasses, a spring and guards forming members which areinterlocked by projections formed on one member and passing IOO throughand extending beyond said member, 1n testimony whereof I affix mysignature in posts with receptacles adapted to receive the presence oftwo Witnesses. interlocked members and the extended end of theinterlocking projections, and locking- 5 plates introduced into thereceptacles in man- Witnesses:
